Hengyang - Gold Ore Procssing Plant
To roll crusher (double roll crusher) applied in cement chemical industry electric power mining metallurgy building materials refractory materials coal and other industries brittle massive materials coarse medium crushing the material size. Flotation is suitable for processing the gold-bearing sulfide ore which with fine and floatable gold particles, during flotation , sulfide ore act as the carrier of gold and is enriched to sulfide mineral concentrate. Flotation can be also used to process multi-metal which containing sulfide mineral and carbonic mineral . For the mineral insoluble that can t be processed by amalgam or cyanidation , which should use a combined process that including flotation .
Introduction
Grinding fineness , pulp concentration , reagent dosage , inflating volume , flotation time are the influence factors for flotation process . Normally, these process conditions should be confirmed by mineral processing test and practical experience .
Process flow
Flotation process has the most important influence for gold flotation , to choose the rational process depends on the nature of ore, and should also consider the facility of operation , cost and the recovery.
For the gold mining that contains only one mineral with gross particles and embedded uniform , usually use one step grinding and flotation process . For the gold particles have diversity sizes and embedded uneven in the gold ore , normally put mercury plate and gravity equipment to pre-recover the gold particles in the grinding and classifier circuit before carry on the flotation process . These two process above are widely used in gold dressing plant But for the gold ore with complicated mineral, flotation process will be more complex, for example, separation process in grinding , mud and sand separation process are all applicable in practice . For flotation in polymetallic ore , its process will be more complex , gold enrich normally in some concentrates , and is sold as an associated mineral.
